A strange package and a cracked wooden cage completely broke the ordinary life of courier Qiao Xu. Accidentally breaking into the secret realm of the cage, he discovered that it was actually a spiritual cage that could "raise spirits" - skinny stray cats recovered and evolved, ordinary mice mutated into ferocious beasts, and the words "Adopt what you want" engraved on the cage turned out to be a fatal curse.
The frequent appearances of the mysterious woman Lin Wan, the strange tracking and feeding, hide a conspiracy spanning twenty years; the secret notes left by his father, Zhou Wenyuan's ambition, and Wu Shouyi's double betrayal gradually revealed the secrets of the longevity lock and the gluttonous seal.
The road to nourishing the soul is also the road to eating the heart. When the spirit cage backfires, the gluttony is about to come out, and the three keys gather together, Qiao Xu realizes that from the moment he took over the cage, he has already entered the whirlpool of fate - he must eventually pay for the sins committed by the spirit keeper. And behind the seal of the Immortality Lock, there are still the remaining souls of the Taotie that have not dissipated, and a catastrophe that has not yet ended...
